BACKGROUND

Cable installers are commonly required to carry cable to installation locations. The installers usually use some type of shoulder bag or other types of packing solutions with an opening for paying out the cable. These cables are often wound on a reel to form a cable coil and packaged in a box or bag for payout during installations. The installer may, however, payout too much cable if the installer pulls too hard on the cable.

Therefore, a need exists for a cable reel that allows for easy installation of cable in a bag or the like and that prevents overpayout of the cable.

The present disclosure relates to a method of installing a coil of cable in a bag, that comprises the steps of: placing a coil of cable on a first hub of a first flange of the cable reel; placing a second flange of the cable reel, that is separable from the first flange, opposite from the first flange to hold the coil of cable on the first hub of the first flange; positioning the first flange on or next to a first support frame received in the bag; and placing the second flange on or next to a second support frame received in the bag. The second support frame is positioned in the bag such that the first flange, the coil of cable and the second flange are located between the first support frame and the second support frame.

The present disclosure relates to a method of installing a coil of cable in a bag, that comprises the steps of: placing a coil of cable on a first hub of a first flange of the cable reel; placing a second flange of the cable reel opposite from the first flange to hold the coil of cable on the first hub of the first flange; positioning the first flange on or next to a first support frame located in the bag; and placing the second flange on or next to a second support frame located in the bag, wherein the second support frame is positionable in the bag such that the first flange, the coil of cable and the second flange are located between the first support frame and the second support frame. The step of placing the coil of cable on the first hub of the first flange occurs before the step of positioning the first flange on the first support frame.

The present disclosure relates to a method of installing a coil of cable in a bag, the bag having a cover for opening the bag, a base opposite the cover, and sides extending between the cover and the base, the comprises the steps of: placing a coil of cable on a first hub of a first flange of the cable reel; placing a second flange of the cable reel, that is separable from the first flange, opposite from the first flange to hold the coil of cable on the first hub of the first flange; positioning the first flange on or next to a first support frame received in the bag, the first support frame being on an inner surface the base of the bag; and placing the second flange on or next to a second support frame received in the bag, the second support frame being on an inner surface of the cover of the bag. When the cover of the bag is closed, the first flange, the coil of cable and the second flange are located between the first support frame and the second support frame inside the bag.

Referring to FIGS. 1-3, 4A, 4B, 5A, 5B, and 6-8 , the present disclosure relates to a cable reel 100 that may be carried in a conventional shoulder bag or satchel, a cardboard or plastic box, and the like 101, with an opening 103 for easy payout of cable supported on the cable reel. The cable reel 100 according to one example of the present disclosure is designed to provide easy installation of cable C, such as a cable coil, on the reel 100 and also prevents overpayout of the cable. Because the cable reel 100 is designed to be carried by an installer, it is preferable that the components of the cable reel 100 be formed of lighter weight materials, such as plastic. Some exemplary plastic materials include polyethylene, polypropylene, ABS or other polymer products.

As seen in FIG. 1 , the cable reel 100 generally includes opposing support frames 102 and 104 that rotatably support first and second flanges 106 and 108 with a hub member 110 therebetween on which the cable is held. A braking mechanism 112 is preferably provided on the reel 100 between the support frames 102 and 104 of the flanges 106 and 108 to limit overpayout of the cable. The cable reel 100 may be inserted into and supported by the payout bag or box wherein the support frames 102 and 104 are attached, preferably removably attached, to the cover and base, respectively, of the bag.

As seen in FIGS. 2 and 6 , each support frame 102 and 104 includes an outer frame portion 120 with one or more cross members 122 and a middle flange support 124. The outer frame portion 120 may have a substantially square geometry. The middle flange support 124 includes an annular extension 126 (FIG. 6 ) that supports a first part of the braking mechanism 112. The first part of the braking mechanism may be an outwardly extending gear member 128 that includes a plurality of annularly arranged teeth 130 extending radially outwardly from the annular extension 126.

The middle flange support 124 and gear member 128 are offset or off-center on the frame such that the distance d₁ (FIG. 2 ) to one end 132 of the frame is longer than the distance d₂ (FIG. 2 ) to the opposite end 135 of the frame. This offset provides a gap 134, as seen in FIG. 8 , in the braking mechanism 112. Indicia 136, such as a company name, may be provided on the end 132 of the frame to indicate the longer side, that is distance d₁ of the frame to facilitate the orientation of the cable reel 100 in the bag or box.

Each flange 106 and 108 is preferably sized to fit within the outer frame portion 120 of its respective support frame 102 and 104 and is sized to accommodate the cable, such as a cable coil. The cable coil may be, for example, having an outer diameter of 345 mm and an inner diameter of 200 mm and a height of 135 mm. The flanges 106 and 108 are preferably disc-shaped. Each flange has inner and outer surfaces 140 and 142 and a central arbor opening 144. The inner surface 140 of each flange abuts the hub member 110 and the outer surface 142 abuts a respective support frame 102 and 104.

The central arbor opening 144 corresponds to the middle flange support 124 of each respective support frame. The central arbor opening 144 supports the second part of the braking mechanism 112 has seen in FIGS. 3 and 7 . The second part of the braking mechanism 112 may be an internal gear member 146 that includes a plurality of annular arranged teeth 148 extending radially inwardly.

The hub member 110 is located between the flanges 106 and 108 and supports the cable coil. The hub member 110 includes a first hub portion 150 (FIGS. 4A and 4B) and a second hub portion 152 (FIGS. 5A and 5B) that are axially aligned and configured to mate with one another. The hub portions 150 and 152 may be formed separately from the respective flanges 106 and 108 and attached thereto or the hub portions 150 and 152 may be formed as one-piece with the respective flanges 106 and 108.

As seen in FIGS. 4A and 4B, the first hub portion 150 is preferably the base of the cable reel and provides the main support for the cable. As such, the first hub portion 150 is larger than the second hub portion 152. The first hub portion 150 includes an elongated wall 154 that extends from the inner surface 140 of the first flange 106 and defines an inner area 156 that receives the second hub portion 152. The elongated wall 154 has a tapered outer surface 158 that tapers inwardly from the flange inner surface 140 to the free end 160 of the wall 154. Slots 162 in the elongated wall 154 create flexible segments 164, which engage both the second hub portion 152 and the cable coil to retain the same. A groove 166 (FIG. 4B) may be located at the base of the elongated wall 154 to provide additional flexibility to the segments 164. Any other mechanism may be provided to add flexibility to the segments 164. For example, the segments 164 can be made thinner.

Secondary engagement members 170 may be provided as a back-up to retain the hub portions 150 and 152 together. The secondary engagement members 170 may be, for example, one or more snap arms 172 provided in the inner area 156 that extend from the flange inner surface 140. The one or more snap arms 172 preferably extend beyond the elongated wall 154 of the first hub portion 150, as seen in FIG. 4A, in order to engage the second flange 108. The ends of the snap arms 172 preferably include snap tabs 174 that engage corresponding slots 176 (FIG. 5B) in the second flange 108. Although a snapping engagement is preferred to secure the hub portions 150 and 152 together, any known interlocking mechanism may be used.

As seen in FIGS. 5A and 5B, the second hub portion 152 includes a truncated wall 180 that extends from the inner surface 140 of the second flange 108. The truncated wall 180 has a tapered outer surface 182 that fits inside of the elongated wall 154 of the first hub portion 150 to form a friction fit between the hub portions 150 and 152 and expands the flexible segments 164 of the first hub portion 150.

As seen in FIG. 8 , the braking mechanism 112 is provided by meshing the teeth 130 and 148 of the outer and internal gear members 128 and 146. The gap 134 between the teeth 130 and 148 provides clearance for the teeth to slip or jump when the cable is pulled from the reel. The gear members 128 and 146 prevent overpayout of the cable. More specifically, when the cable is pulled from the reel, the flange 106 and 108 rotate, thereby making the gear teeth 148 rotate. The side support 120 is preferably fixed inside of the supporting bag or box and therefore does not rotate. This causes the gear teeth 148 to override meshing gear teeth 130 on the side support 128 which creates friction and provides a braking to the momentum of reel if the cable is pulled too hard. This action also creates a clicking mechanism which in turn prevents overpaying the cable.

The distance of the gap need only be long enough to provide a clearance to have gear teeth 148 to override teeth 130, thereby allowing the braking mechanism to work. This clearance distance could vary depending upon the gear teeth depth, flange hole inner diameter, side support gear depth, and the outer diameter of the middle flange support 124. The gap 134 may be, for example, about ¼ inch.

To install the cable on the cable reel 100, the cable coil C is placed over the first hub portion 150 of the hub member 110 and on the first flange 106 so that the first hub portion 150 extends through the inner diameter of the cable coil. The cable coil C may be prepacked in a plastic shrink wrap or with tie wraps or combination of both without any external structure to support that coil. Next the second hub portion 152 is inserted inside of the first hub portion 150 to frictionally engage the same and expand the flexible segments 164, thereby forcing the flexible segments 164 to engage the inner diameter of the cable coil. The locking tabs 174 are then inserted inside of the slots 176 on the second flange 108 to hold two flanges and hub portions together.

In an example of the present disclosure, the first support frame 102 of the reel 100 is secured to the base of the bag or box, such as by straps, such as via strap 105 (FIG. 1 ), and the second support frame 104 is secured to the cover or flap of the bag. With the cable coil installed on the hub member 110, the cable coil is inserted into the bag or box between the support frames 102 and 104 in the bag or box. The assembly of the hub portions 150 and 152, the flanges 106 and 108, and the cable coil is preferably inserted into the base of the bag on its side such that the middle flange support 124 of the frame secured to the base of the bag fits inside of the central arbor opening 144 of the flange. Similarly, the middle flange support 124 of the frame secured to the cover of the bag fits inside of the opening 144 of the other flange when the bag is closed. Once the frames 102 and 104 are mated with the flanges 106 and 108, respectively, the operator can then dispense or payout the cable through a cable payout slot or opening in the bag or box. The operator may open the cover of the bag or box to separate the hub portions 150 and 152 by disengaging the snap tabs 174.

It will be apparent to those skilled in the art having the benefit of the teachings presented in the foregoing descriptions and the associated drawings that modifications, combinations, sub-combinations, and variations can be made without departing from the spirit or scope of this disclosure.
